Diabetic ketoacidosis and covid-19: Two case reports

Background: COVID-19 is a viral infection that causes pneumonia with dyspnea, cough, and fever. Its outcomes are more severe in patients with diabetes, hypertension, and other disorders than in healthy people. New-onset diabetes and diabetic ketoacidosis (DKA) have been reported as the complications of COVID-19 in several studies. It seems that the prevalence of DKA due to Covid-19 is increasing. Therefore, two cases of individuals with DKA due to COVID-19 are presented in this study to inform other researchers about the details of this phenomenon. Material and Methods: Demographic characteristics, medical histories, physical examinations, laboratory investigations, real-time RT-PCR tests, computed tomography (CT) imaging studies, given treatments, clinical courses, and management outcomes were documented prospectively. Results: In the present experience, the manifestation of COVID-19 disease in the second case with a history of diabetes was more severe than in the first case. In the second case, with underlying diabetes and COVID-19, the DKA manifestation was associated with consciousness loss, severe restlessness, and respiratory distress; however, in the first case, with COVID-19 without diabetes, the DKA manifestation was associated with anorexia, weight loss, and lack of respiratory distress, which were milder symptoms than the second case. Conclusion: Due to the high prevalence of diabetes mellitus and COVID-19 in Iran, it is recommended to raise awareness of DKA symptoms among health professionals.
